Bash opening session

1. Instructor / helpers / course introduction.
2. Distribute the usernames and passwords.
3. Let’s try to log in to the training cluster.
4. Review the program for this morning: you have 1h15m of materials to read/watch until 11:30am Pacific.

By mid-day you should be comfortable with:

• creating and deleting files and directories, copying and moving them
• writing text into a file and printing its contents to the terminal
• working with tar archives
• copying files to/from a remote server
• redirecting output to a file
• using Unix wildcards (* character)
• using pipes to construct longer commands
• working with Unix loops

Some of the hands-on exercises we will do in the mid-day Zoom session:

• Many exercises on navigating the filesystem.
• Combine ls and head into a one-line command to show three largest files (by the number of bytes) in a given directory.
• Write a one-line command to show the name of the longest (by the number of lines) *.pdb file in the current directory.
• Working with environment variables.
• Write a loop to rename all *.txt files in a given directory to *.bak files.
• Write a loop to replace spaces to underscores in all file names in the current directory.
